SPECIFICATION forming part of Letters Patent No. 381,532, dated April24, 1888.

Application tiled August 5, 1887. Serial No4 246.215. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM WALLACE GULLY, a citizen ot" the UnitedStates, residing at W'ilson, in the count-y of Ellsworth and State ofKansas, have invented a new and useful Improvement in Pumps,of which thefollowing is a specification.

My invention relates to an improvement in pumps; and it consists in thepeculiar construction and combination of devices,that will he more fullyset forth hereinafter, and particularly pointed out in the claim.

The accompanying drawing is a vertical sectional view of a pumpembodying my improvements.

A represents the vertical rectangular box which forms the pump-stock.The said box is open on its front side, and has its rear side partlyclosed by a board, B, arranged at the upper end of the box.

C represents the pump-barrel, comprising the upper and lower woodensections, D and E, and the cylindrical sleeve F, connecting the ends ofthe upper and lower sections, and the similar sleeve, G, attached to theupper sec tion and projecting upwardly in the stock. The lower section,E, rests against the bottom of the well and is submerged, and isprovided with a series of inlet-openings, H. On the upper end of thesaid lower section is formed a valve-seat, I; and K represents movablevalves arranged in the lower end of the sleeve F,and adapted to open andclose the opening in the valve-seat.

In the board B is made a vertical opening, L, through which extends theinner end of a lever, M, fulcrumed on a pin, N, extending transverselythrough the bore. To the inner end of the lever M is attached asuspended cylindrical air-chamber, O, the lower end of which is providedwith a packing, P,that tits snugly in the upper portion of the uppercylindrical sleeve, G. Thelower end of the airchamber is open, and isprovided with abridge, R, to which is attached the upper end of apump-rod, S. Thclower end of the said pumprod extends downward throughthe bore ofthe section B, and is provided with a plunger, T, having apacking,U, that tits snugly against the side of the lowersleeve, F, andthe said plunger is provided with outwardly-opening valves U'.

From the foregoing description it will be understood that thepump-barrel is immovable, and that the air-chamber is adapted toreciprocate in the upper portion of the pumpbarrel and to impartreciprocating motion to the plunger when the pump-handle is operated.

V represents a weight, which is suspended from the outer portion of thepump-handle by a rod/Vthc said weight serving as acounterpoise for thereciprocating air-chamber and the plunger.

The operation of my invention is as follows: On the upstroke of theplunger the valves U are closed and the valveK is opened, therebycausing the plunger to create apartial vacuum in the lower sleeve, F,and suck a sufficient quantity of water to till the said sleeve. On theensuing downstroke of the plunger the valve K is closed and the valves Uinl the plunger opened, and the water below the plunger in the sleeve Fis forced upward th rough the central opening in the plunger and outthrough the valves U into the upper portion of the pump-barrel. At thesame time that the plunger descends the air-chamber deseends also, thuscompressing air above the column of water in the pump-barrel,and causingthe water to be discharged through the spoutY in a continuous stream.From the foregoing it will be understood that the pump alternately liftsand forces the water at alternate strokes, and thereby the pump isspecially adapted for use in deep wells.

The counterbalancing-weight is hung in the well, below the coverthereof, as shown, the suspending-rope passing through an opening insaid cover. Thus the weight cannot swing and injure the person operatingthe leverhandle. The wooden section E acts as a strainer and preventsthe lower valves from clogging. The weight of the air-chamber O wouldrequire too violent exertion in addition to that of the pump-rod plungerand Water, when depressing the lever-handle, but for thecounterbalancing-weight V, which makes the lever-handle M work easily.The counterbalance, therefore, is an important part of the pump.

Having thus described my invention, I claim- The pump-barrel composed ofthe wooden sections D E, the metallic cylindrical section connected tothe lower end of the rod S, sub- F, connecting them, andthe metalliccylindristantiall y as described.
